need to transfer routes to other GPS devices

On my Garmin Edge 205 I have made lots of routes and uploaded them to my account in Garmin Connect. In the detailed page of each route (a/k/a/ activity) there is a menu option called “Send to Device.” I want to transfer my routes to another GPS device, presumably via the “Send to Device” option.

MY QUESTION:
Is the "Send to Device" option limited to transfers to another Garmin Edge 205 or to any device? If any device, which GPS devices (products) are capable of receiving the transferred routes AND displaying them on a map with arrows to guide the rider through the route, and indicators to show if the rider made a wrong turn? I’m preferring devices that hold more than 10 routes at a time.

The “Send to Device” button says that it allows you to “(1) Follow the Course of an activity on enabled devices. “ I presume this means follow the map of the route I had made and transferred to the other device.

The “Send to Device” button also says that it allows you to “2. Enable Virtual Partner and track yourself against the activity owner.” WHAT DOES THI S MEAN?
